COMBINED TOP FEED AND RUFFLING MECHANISM FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Oct. 9, 1917.

Application filed February 21, 1916. Serial No. 79,511.

To all whom it may concern:

Be it known that I, JOHN P. VVEIS, a citizen of the United States, residing at Nyack, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Combined Top Feed and Rufiiing Mechanism for Sewing-Machines, of which the following is a specification.

This invention relates to sewing machines, the object of the invention being to provide a combined top rufiling and feeding mechanism in which each has a fourmotion action, the top feed and rufiiing mechanisms being so constructed and organized that the feeding stroke of either the rufiier blade or the top feed dog may be changed instantaneously one independently of the other or simultaneously so as to vary its action on the work; that is to say, the controlling means for each of these parts may be 0perated independently of the other, or they may be so connected as to operate-together so that the feeding stroke of the top feed can be changed at the same time that the feeding stroke of the ruflling mechanism is changed, and this by the mere shifting of the foot treadle, so that the character of work may be controlled while the stitching proceeds.

An object of the improvement is to provide in a single machine practically three feeding mechanisms, a bottom feed acting on the material in front and rear of the needles, a top pull feed located in the rear of the needles, and a top rufiiing mechanism located to act on the material in the front of the needles, togetherwith a strip folder and hemming device or other attachment suited to the character of work to be produced.

A further object of the invention is the .provision of a combined four-motion top ruffling and feeding mechanism comparatively simple in construction'and efficient 1n operation, and which may be readily assembled with the several parts of a sewing machine.

This invention is particularly useful in connection with the joining of bibs to overalls, where a. lining strip is stitched on the bottom to cover the raw edges and a hennner is used to turn the edge of the overall while the bib is stitched thereon. The rufliing mechanism assists in starting the work to the needles and overcomes the stretch, while the back top pull feed enables the machine to handle very heavy, bunchy, bulky work, as in the overall work described. There are places, as for instance on the fly, where some twelve or more thicknesses of material must be stitched, which has heretofore offered great ditliculties. The same obstacles have been presented in connection with the stitching of the skirts to the waist portions of house dresses and applying a band at the same time, especially where a cluster of the ruflles is necessary at certain parts of the garment, and also the stitching of cuffs to working shirts and the like.

In the drawings accompanying and forming part of the specification, Figure 1 is a rear View of a Metropolitan sewing machine having a top and bottom. rotary shaft with my improvement applied thereto; Fig. 2 is an end view of the right-hand end of the machine shown in Fig. 1, showing the details of the top feed and rufiling mechanism; Fig. 3 is a detail perspective View of the ruflling bladeand its actuating means; Fig. 4 is a front view of the right-hand end of the machine shown in Fig. 1, or looking in the direction of the arrow in Fig. 2; Fig. 5 is a rear end'or left-hand view of Fig. 1, looking in the direction of the arrow in said Fig. 1; Fig. 6 is a detail perspective view of the top feed dog and its holding means; and Fig. 7 is a perspective detail view of the presser foot, showing the feed slots for the top pull feed.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

The stitching and bottom feed mechanisms ma -be the same as those generally used in etropolitan sewing machines and are well known in the art. and therefore need not be herein described at length.

The machine base 1 carries the bottom rotary shaft 2, on which are mounted the combined belt and hand wheel 3 and the vertical arm 4 in which the connections operate between the bottom shaft and the top shaft 5 located in the overhanging arm 6. This top connected with a pitman 10, (see Fig. 2),.

the lower end of which is connected as at 11 to the needle bar 12 to reciprocate the same in its bearing 13 carried by the machine head 14. A suitable needle holder 15 is secured to the end of this needle bar and carries the needles 16. A thread take-up rod or extension 17 is connected with the needle bar, as at 10', and reciprocates therewith. The bottom shaft 2 endwise reciprocates a looper shaft 18 located in parallelism therewith through bevel gear connection 19, while this looper shaft is rocked by an eccentric connection 20 also carried by the shaft 2. The other end of this eccentric connection 20 is connected for movement to the looper shaft crank 21, (see Fig. 4), so that the looper holders 23 carrying the loopers 24 have a four-motion movement cooperating with the needles to make a double chainstitch. The looper shaft 18 operates in bearings 25, while the crank shaft 26, with which the bevel gears 19 are connected, operates in bearings 27, one only of which is in sight, and by reason of a fork 28 engaging with this crank shaft 26 the looper shaft 18 is endwise reciprocated. A cloth plate 29 supports the work and also a hemmer attachinent 30, which is raised slightly from the plate to permit one portion of the goods to be fed there-under, while a strip folder 32, which is also secured at 33 to this cloth or slide plate, guides the strip to the stitching mechanism to be stitched to the bottom of the work.

The presser foot 34, (see Fig. 7), is cut out as at 35 and has ears 36 to assist in guiding the work. The foot also has vertically extending lugs 37 provided with holes 38 for securingit to its shank 39, (see Fig.

2). This shank is pivotally secured to the presser bar 40, which slides in a bushing 41, which is secured to'the machine head 14. A presser bar guide 42 is secured to the presser bar, as at 43, to prevent axial movement of the same, and it also provides a means for lifting the presser bar through the aid of a hand lifter 44 operating there-- under and through the aid of a vertical angle rod 45 extending upward from said guide which coacts with a foot lifter lever 46. This lever 46 is pivoted at 47, (see Fig. 1), to the overhanging arm 6, and is operated by a rod 48 extending down to and connected with a foot treadle, (not shown). A spring and collar 49 holds the parts in normal position when not in use. The presser foot 34 is slotted, as at 50, to receive the top feed dogs 51. which are provided with teeth and vertical walls 52 having pin holes 53 to receive pivot pins 54 for pivotally securing them to their shanks. Each of these shanks has a vertical stem 57 adjustably se nae-2,4022

cured to a plate 58. This plate terminates in an ofi'set extension 59 adjustably secured to a top feed bar 60, as at 61. This top fee-d bar is pivotally connected at 62 with a lever 63, which in turn is secured to a rock shaft 64. This rock shaft extends along the back of the machine and operates in bearings 66, one at each end, and is actuated by a curved arm 67 secured to the shaft, as at 68. A slide block 69 is mounted and may be shifted on this curved arm 67. This slide block has pivotally secured thereto an arm 71 reaching over and connecting with an adjustable crank 73 carried by a disk 74, which may be part of the top shaft 5. The top feed bar 60 is shown as a three-armed member, with its third end pivotally connected to a vertical link 76 extending upward through a slot in the head back of the presser bar bushing 41, (see Figs. 2 and 4),

with its upper end pivotally connected to a pin 79 for swinging movement. This pin 79 operates vertically in a slot 80 of a yoke 81. which is secured to the presser bar 40 for movement therewith, so that when the presser bar is lifted it will lift this pin and the parts connected therewith, to wit the links 76 and 96, and thereby the top feed and ruffler. A presser bar spring 82 has one end resting on top of the presser bar and its other end 83 resting on a lug carried by the top arm 6, a pressure regulating screw 84, (see Fig. 1), being provided to adjust the pressure of the presser foot on the work. The needle bar driving crank 9 has an arm 85 which carries a crank pin 86 projecting into a lug 87 shown as a part of a barrel 88 in which a spring 89 is located, (see dotted lines, Fig. 3), and this spring co-acts with a plunger or piston 90 to give downward pressure to the top feed and ruiiier blade. A pin 91 is carried by the plunger and projects into a slot 92 to limit movement of the plunger, which has a vertically extending stem 93 carrying a nut 94. This plunger is provided with a slotted end 95, (see Fig. 3), which carries the pin 79 hereinbefore referred to and which pin co6perates with the yoke 81 secured to the presser bar 40, and this slotted end receives a swlnging arm 96, which is also pivotally secured therein by said pin 7 9 so as to swing. This swinging arm has a yoke 97 adjustably secured to its lower end for adjustably supporting a rufller blade and its bar 98. A link connection 99 couples this swinging arm 96 with a rocker arm 100, (see Figs. 2, 3 and 5), for in and out movements. This arm 100 is secured at its upper end to a rock shaft 102 which rocks in suitable bearings 103. This rock shaft 102 extends along the front side of the overhanging arm 6substantially opposite the rock shaft 64 at the rear side thereof, and is provided at its opposite end witha curved arm 104 having a slide block 105 mounted thereon and to which is pivotally connected an arm 107 connected with the adjustable crank 73 of the disk 74. Coiled springs 108 and 110 connect the arms 71 and 107 with a post 109 and normally hold the slide blocks 69 and 105 against stops 111 carried by the arms 67 and 104. Duplicate rods 112 are provided for shifting the blocks 69 and 105 on the curved arms as desired, and a connection 113 couples the bottom ends of these rods 112 so that both may be operated at the same time by the chain 114 connected with a foot treadle 115, (see Fig. 5), or this connection 113 may be omitted and the chain 114 connected with either of the rods 112 if desired, and a knee shift used to operate the other rod 112, as the case may be. Adjustable stops 116 are secured in extending portions 117 of the rock shaft bearings 66 and 103, with screws 118 to clamp the same in position, and the right-angle portions 119 of these stops provide means for limiting the downward movement of the blocks 69 and 105. By adjusting thestops 116 to 'diiierent positions as, for instance, one lower than the other, the bar 113 will assume. an angular position to meet such adjustments, thus permitting different or independent differential control of the top feeding instrumentalities.

From the foregoing it will be seen that I have provided a new combination of feeding elements which have broad adaptability in view of the fact that a feed dog may be substituted in place of the. rufiling blade 98, so that a" push and pull feed in connection with the bottom feed can be used, making it possible to feed over any irregularityv of seam and bunches etc. in the work without difiiculty. On the other hand, cluster ruflles of bulky material present great diificulty in feeding, and this improved feed overcomes this. It also overcomes stretching of the work, as there need be very little pressure on the presser foot and the top and bottom plies of work may be brought out evenly, or for special kinds of work the stroke of the rufiiing blade and the top feed may be such as to cause thetop ply to come out uneven with the bottom ply. The top feed and ruiiling mechanisms are of the differential class, as one may have a different movement from the other, although operated by the same means. The shifting of the crank 73 to and from the center varies the throw. of both the top feed and ruflier, while the shifting of the blocks69. and 105 along the curved arms 67 and 114 give a range of adjustment to meet other conditions. In other words ifthe sliding blocks 69 and 105 are pulled downward, the movement of the instrumentalities is increased, that is, they move to a greater extent. If the slide blocks are forced to the highest position on the curved arms, the instrumentalities are ineffective on the work in the Sense that if the normal feeding action of the bottom feed is inch per revolution of the machine and the normal action of the instrumentalities is equal to the main feed, then they are practically ineflective because the machine would do the same work without them, but when the slide blocks are brought to a lower posi tion on the curved arms, then their action is increased with respect to the main feed and they become effective on the work. Instantaneous control of' these mechanisms may be efl'ected by a simple movement of the operators foot or a shifting movement of the knee, affording a very flexible control.

The liftinglmotion of the top feed and rufiier effected by the crank pin 86 enables the feed and rufller to step over scams or other raised uneven portions of the. goods and eliminates back drag, so that the stripper blades usually employed on ruflling ma chines are unnecessary. This is an important feature because they are usually in the way of the attachments and interfere with the rapid handling of the work and also exert friction on the' feeding of the ma terial.

It will, of course, be understood that the various details may be more or less changed without departing from the spirit or scope of this improvement.
